Methods for determining an analyte concentration using signal processing algorithms

摘要

A method for determining a glucose concentration using a test strip having a working electrode and a reference electrode, the method includes: applying a test voltage between the working electrode and the reference electrode; measuring a plurality of test currents when applied to the test strip a blood sample containing glucose; calculating a correlation value glucose (Y) using an equation that is ** ** Formula where tF1 is a starting point of a first predetermined time interval, TL1 is a predetermined end point of a first time interval, tF2 is a starting point of a second predetermined time interval, tL2 is a predetermined end point of a second time interval, I (t) is a current as a function of hematocrit h, glucose G and time t q (t) is a correction function of time t, where time points of start and end of the time intervals are determined and optimized to reduce the effects of hematocrit; and calculating the glucose concentration based on the correlation value glucose (Y).
